I bought the Fits Wunderbreech to reduce visible panty lines under tan knee-patch breeches. I am 5'5 and 145lbs and bought the large. The sizing is appropriate. The wunderbreeches themselves were comfortable and I think they would have been breathable. However, I am not impressed with the ability of the wunderbreech to reduce visible panty lines or cellulite. Perhaps if you had a ton of cellulite it might reduce it a little bit. Guess I will continue my search for a visible panty line reducer. :(
These are sooo awesome!! They smooth out panty lines and hold in "lumps and bumps" without making you look or feel stiff. The thin fabric is suprisingly supportive, without adding any thickness under breeches. I used to be a little worried about how my behind looked especially in light-colored breeches, but with the support and smoothing benefits of Wunderbreech, I feel more confident about my "derry-air".
